Option C
For each value of y, -2 is a solution of -21 = 6y - 9
<u>Solution:</u>
Given, equation is – 21 = 6y – 9
We have to find that whether given set of options can satisfy the above equation or not
Now, let us check one by one option
<em><u>Option A) </u></em>
Given option is -5
Let us substitute -5 in given equation
- 21 = 6(-5) – 9
- 21 = -30 – 9
- 21 = - 39
L.H.S ≠ R.H.S ⇒ not a solution
<em><u>Option B)</u></em>
Given option is 3
- 21 = 6(3) – 9
- 21 = 18 – 9
- 21 = 9
L.H.S ≠ R.H.S ⇒ not a solution
<em><u>Option C)</u></em>
Given option is -2
- 21 = 6(-2) – 9
- 21 = - 12 – 9
- 21 = - 21
L.H.S = R.H.S ⇒ yes a solution
<em><u>Option D)</u></em>
- 21 = 6(9) – 9
- 21 = 54 – 9
- 21 = 45
L.H.S ≠ R.H.S ⇒ not a solution
Hence, the solution for the given equation is – 2, so option c is correct

Answer:</h2>
<u>The diameter of circle is </u><u>288.84 units</u>
<h2>
Step-by-step explanation:</h2>
As we know
Circumference of circle = 2*pi*r
where r is radius of the circle
Arranging the equation
C = 2 π r
r = C / 2 π
r = 907.46 / 2 π
r= 144.42
Since Diameter is double of radius so diameter is 2 x 144.42 = 288.84 units
Answer:
No
Step-by-step explanation:
The rule to see if 11 is divisible is subtract the last digit from a number made by the other digits. If that number is divisible by 11 then the original number is, too. If you apply that rule then you see that it is not divisible.
